i have a 2000 e150 5.4...my heater core is leaking there are 2 hoses that attach to it. i need to clamp it off until i can get my new core on friday anyone know which one to clamp to stop the flow temporarily. there are 2 a top one and bottom one thanks for any help in advance

 

Take both hoses off of the heater core and connect them together you can get the part you need at a parts store just tell them what you want to do..

 

Econoshorty has this right---in fact EITHER hose will let coolant flow through the heater core so joining them temporarily is the best cure for now.

I'll also suggest NOT replacing the Quick Lok hose fittings Ford uses---cut them off at the very end and use stainless steel worm clamps instead. I'd suggest replacing the two heater hoses too especially if they're original.

Replacement formed hoses with the factory style Quick Lok fittings run about $60-70 each which is ridiculous considing they're easily replaced with standard hose and fittings.

Changing the core isn't the easist of jobs but it's doable--took me about 3 hours start to finish. I was already inside the heater core interior box to replace the blend door and drive motor so though WTH--why not just save the effort and catch it all at one time.

Its aggravating but be patient----you'll do fine!

 

Im having the same problem right now. Any ideas on how to get the quickloks off?

 

I believe Lisle makes an inexpensive set of plastic Quick-Lok fitting tools---allow you to remove them somewhat easier. My method for removal basically destroyed the locking parts which wasn't the smartest thing to do. Were I to do this again I'd get all new locking parts which consists of two each plastic "locks" and O rings suitable to the two different hose sizes. Cost was about $30 from Ford stealership but they might be generically available too.

Here's a link to another thread about this---there is also yet another link which gives even more detailed info on heater cores in our vans:

A search for "heater core" in the van sub-forum might have even more info too.

First time seems such a hassle until you've actually done it-----you learn a lot in a short time. Good luck--let us know how it goes for you.

 

When I did my heater core in our 1992 Club Wagon I found the Quick-Lok fittings would not budge off the heater core tubes, even while using the correct tool. I solved the problem by grabbing the old heater core and pulling it out of the heater box until I got it out far enough to use my sawzall to cut the old tubes off the heater core. With the tubes off the core it was easy to pull the hoses out of the firewall and into the engine compartment where the improved access made removal of the hose from the tubes a snap. I suppose at this point if one was in a bind they could daisy chain the two tubes together using a length of heater hose or perhaps by using a copper tube fitting and soldering them together until the new core arrived.

I was going to go the hose clamp route but found I just did not have adequate access to the firewall to get in and tighten the clamp. I ended up refitting the hoses with new Quick-Lok parts from Ford. The parts cost was way more than a couple of hose clamps would have been but JWAs' quote of $30.00 seems about right. Its been years but as I recall all I needed to do was lightly lube the fittings with something, I believe it was vaseline, and the fittings slid right on.
